Speciation traits of paramere, paraproct and aedeagus were applied to find initial split criteria with fine structure analysis in order to prepare diverged trait matrices for delimiting phylogenetic incipient species of unsettled limnephilid taxa in the early stages of reproductive isolation. A brief history is presented how this phenotypic taxonomic tool of the speciation traits was discovered and applied in caddisfly taxonomy. The theoretical basis was elaborated for the phenotypic speciation trait by reviewing several relevant topics in the sciences of taxonomy, molecular genetics and phylogenetics. Perspectives of integrative taxonomy is discussed in context of phenotype versus genotype, immensely complex phenotype versus phenomic challenge, taxonomic impediment versus genetic expedient, taxonomic adaptation of genetic vocabulary versus genetic sophistication and virtualization, New Systematics of Huxley and Mayr versus New Taxonomy of Wheeler. Debates on magic trait, speciation phenotype, speciation trait and super traits are discussed concluding that evolution works with phenotype and why the cryptic species concept is irrelevant. Briefly summarized how speciation traits evolve in sexual selection, through accelerated reproductive isolation with genital evolution through sex-limited speciation traits, including minor sex chromosomes. Why neutral molecular markers are blind compared to the adaptive speciation traits sensitized by fine structure analysis and backed by the potential of high-tech and high-throughput phenotyping and cyber-infrastructure broadly accessible and fed by computable phenotype descriptions. What sort of genetics could really help taxonomy to describe biodiversity of the over 100 million unknown taxa? Collecting new and re-examining old type materials deposited in various collections, the following taxonomic actions were elaborated by speciation traits. Drusus bolivari new species complex has been erected with redescription of Drusus bolivari (McLachlan, 1876), with species status resurrection of D. estrellensis (McLachlan, 1884) stat. restit., with description of five new species: D. carmenae Oláh, sp. nov., D. gonzalezi Oláh, sp. nov., D. grafi Oláh, sp. nov., D. gredosensis Oláh, sp. nov., D. jesusi Oláh, sp. nov., D. pyrenensis Oláh & Coppa, sp. nov.

Nectopsyche genus is common in standing or slowly flowing aquatic ecosystems in the New World. Their taxonomy was unduly based too long on forewing pattern that is easily lost in alcohol. In this created taxonomic chaos management projects are unable to determine these beautiful and common animals. We have elaborated a new taxonomy with easy procedure to delineate closely related incipient sibling species without forewing pattern. Our taxonomy enables us to determine specimens collected and stored in alcohol. We have applied the fine phenomics of adaptive speciation traits of the sigmoid profile of the phallicata and of the apicomesal lobe on gonopods. They were combined, if necessary, with nonadaptive neutral traits of the periphallic organs. These adaptive speciation traits are subtle and stable, they are more super than magic. We briefly review: (1) Are speciation traits really subtle? (2) Are speciation traits super or magic? (3) Why neutral traits are variable? (4) Why adaptive traits are stable? We survey the possible adaptive and neutral traits in the Nectopsyche genus. Our adaptive-neutral distinction has potential in character ranking to establish recent pass, contemporary and old historical divergences in coalescence. Applying the adaptive - neutral distinction, as well as the generality, locality and parsimony principles we have elaborated a character ranking sytem for the genus, for the species groups and for the species with a revised lineage structure in the Nectopsyche genus. Six species grous have been characterised and fourty four new species have been described and grouped in the four species groups. (1) N. candida species group: bonta, buzoga, dombora, flinti, garenoa, lenula, obla. (2) N. pavida species group: alma, bobita, capota, hasonla, kifela, kinilta, kurta, laposka, nemritka, nyaka, oliveri, poca, ritka, salka, silva, sima, terda, vagota, valla. (3) N. punctata species group: eka, kurtula, letra, padka, vezna. (4) N. gemma species group: bunka, eltera, flintorum, huzva, iva, kajla, nilta, pohoka, setfela, suta, taga, tarka, tomora. The species of N. argentata, N. cubana, N. gemmoides, N. jenseni, N. punctata and several unexamined taxa probably represent species complexes. An expected comprehensive revision of the entire genus is needed including forewing pattern with fine phenomics. Inevitable are the re-examination of the speciation traits of the old types and to scrutinise the species status of so called widely distributed species applying the fine phenomics of speciation traits.
